[Dnsmasq-discuss] Dnsmasq ignoring "network matching tag" for range - bug?

[krzysztof.kozlowski at kozik.net.pl]

A client requests an address from a dhcp-range which require special user tag ("trusted"). Dnsmasq should ignore this request (DHCPNAK) and give an address from other range. But it does not - it ignores rule "net:XXX" in dhcp-range and give an address from the special range. Why? It shouldn't :/. 

Normally on each request I can see in logs something like "tags: known, trusted" etc. but in this case there are not any these entries.
